What is an AI hallucination?
An AI hallucination is when a language model generates information that sounds confident and plausible but is false, unsupported or made up, such as a nonexistent policy, wrong number or fake citation. It happens because models predict likely text rather than look up facts.
Examples in support
| Hallucination | Risk |
|---|---|
| Invented refund policy | Financial and legal |
| Wrong setup steps | Frustration |
| Fake feature | Lost trust |
How to reduce them
Ground answers in retrieved sources, require citations, let the AI say "I don't know", restrict to approved knowledge, evaluate regularly and keep humans in the loop for risky answers.
